Ag measurematics pvt ltd offers a range of equipments for hydro turbine control. As part of that the company offers water level indicator model awli - 6m. It is ideal for hydro power plant to monitor fore bay and tail race water level. A float and counter-weight suspended over a pulley with the help of a flexible stainless steel wire rope indicate the changes in water level. The microprocessor based circuit of the field unit senses the rotation of the shaft of the optical encoder, calculates the water level and outputs a current signal of 4 to 20 ma proportional to the water level. The field unit is also equipped with a digital display and a key pad. The current output of 4 to 20 ma is connected to the digital indicator.
